School is HARDER than it was thirty years ago??? You are out of your mind. Have you not seen any of those programs where they put modern kids through a sample of 50s/60s/70s education? My boss was a teacher until very recently and he is adamant that it is many times easier today and standards are way lower.
One small example. My daughters have both done A-Level English recently, and weren't even expected to read the whole of their set novels, just a selected couple of chapters. When I did O-Level (GCSE equivalent, mind, not even A-Level) in 1970, our set book was Hardy's "Far From The Madding Crowd", and they expected us to read the whole book - preferably twice - plus as many OTHER Hardy novels we could fit in, for comparison. This was as well as (typically) eight or nine other subjects - in my case French, Latin, maths, physics, chemistry, biology, geography and history - all of which had similar workloads.
I'm not saying I think it should be like that now - times change, and rightly so - but don't tell me it was "easier" back then!
